为分析硅压力传感器基座受力变形对传感器输出性能的影响,首先利用弹性力学理论和板壳理论分析推导了压力传感器方形膜片应力分布,为力敏电阻在应变膜上的布置提供依据;再利用ANSYS进行分析模拟,探究了传感器基座结构变形对应变膜应力差的影响;然后针对减小基座受力变形对芯片受力的影响,对基座结构进行适当优化,并对比仿真分析的结果;最后通过实验测得优化前后的传感器输出数据.结果表明,传感器基座结构优化后,传感器硅芯片中心最大变形量从2.172μm降低到1.819μm,输出误差从0.95%下降到0.60%.

ON THE OPTIIMAL REACTIONS ASSEMBLAGE OF COMPLEX REACTION SYSTEMS

In this paper, the author analyzes distinguishing features of complex reaction systems and single reversible reaction, and optimizes complex reaction systems starting from set theory.The method of constructing the optimal reactions assemblage and calculating the potential maximum equilibrium yield (PMEY) of objective products is proposed here. This paper points out clearly that the euqilibrium yield of objective products calculated by means of conventional method is the global equilibrium yield (GEY).It is not the thermodynamic constraint, and could be exceeded by observed yield of objective products; only PMEY is the thermodynamic constraint. It gives information on potential and possible optimal yield and thereby improving production. This paper also points out the way in which the real complex reaction system approached the optimal reactions assemblage. The new concept of PMEY and optimal reaction assemblage proposed by this Paper is universally applicable for the important complex reaction systems, such as the pyrolysis of alkane to produce ethylene, steam reforming of methane to produce syngas, production of formaldehyde from methanol, epoxidation of ethylene to produce ethylene oxide, hydrogenation of benzene to produce cyclohexane.
